NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed February 6,1906. Serial No. 299.786.

To all whom it may concern:

Be it known that I, CHARLES A. CLARK, a citizen of the United States,residing at Detroit, in the county of I/Vayne and State of Michigan,have invented new and useful Improvements in N on-Refillable Bottles, ofwhich the following is a specification.

My invention relates to improvements in bottle-valves, otherwisecommonly termed what are known as non-refillable bottles.

As indicated, the invention has for its'object principally to guardagainst the unauthorized refilling of the bottle and to carry out thesame in a simple, practical, economic, and effective manner.

Said invention consists of certain structural features, substantially ashereinafter fully disclosed and specifically pointed out by the claim.

In the accompanying drawings, illustrating the preferred embodiment ofmy invention, Figure 1 is a vertical sectional elevation thereof. Fig. 2is an enlarged disassembled view of the several constituent parts of theinvention exclusive of the ball-valve or baffle. Fi 3 is a like view ofthe baffle or globular va ve.

In the carrying out of my invention I produce the bottle-neck 1preferably with a slightly-downward taper or convergence upon itsinterior, and into said neck is suitably wedged a packing 2, preferablyof rubber or elastic material, to permit as it is forced to its finalposition the lower end lat eral extension or flange 2 thereof to embraceor impinge upon the bottle-neck at its contracted or base end, and thusaid against the outward displacement of said packing, &c.

A metal tubular member 3, forming, as presently seen, a valve-seat, isstepped at its upper end, as at 3*, and inserted and effectively held inplace in said packing, and suitably screwed upon the lower step of thestepped portion 3 of said tubular member or seat is a much lighter metaltubular member 4, forming practically an extension of the latter for apurpose presently made apparent. Said tubular extension or member 4 isprovided in its lower portion about opposite the opening and closingpoint of the valve presently described with passages or perforations 4for the passage of the bottle contents into the space intermediately ofthe bottle-neck and the tubular extension or sleeve 4 in the outpouringof said contents.

A valve 5 of peculiar construction housed within the closure or tubularextension 4, is adapted to be seated upon the lower tubular member orseat 3 for guarding the entrance thereto, the latter forming directcommunication with the main or body portion of the bottle, as willpresently more fully appear. Said valve has an annular channel or socket5 opening out through its lower surface and effective to receive thecorresponding top step of the stepped portion 3 of the tubular member 3,thus providing for seating the valve thereon. Said valve has itsthusformed flange 3 effective to surround the upper end of the member 3and its central core portion 3 depending and fitting so closely withinthe latter and aided by other contributory conditions, as weight, &c.,as to prevent the possibility of the passage of sufficient water at thatpoint to float said valve in any attempt to refill the bottle.

Within the tubular member 4 is arranged a baffling-ball 7, preferably ofglass, normally resting upon the valve 5, while the upper end of saidtubular member is somewhat contracted or converged, as at 4, to providefor seating the ball when the bottle is slanted or inverted.

I claim- A device of the character described, having a tubular seatprovided with a stepped upper end, and centrally within said seat with asocket, a valve having an annular channel in its lower end receiving thetop step of said seat and a depending corefitting said seat-socket, anda second tubular member connected to said seat at its lower step andhaving its upper end somewhat contracted or converged and containing abaffling-ball adapted to seat in said upper end when the device isslanted, said second tubular member adapted to guard or inclose saidvalve and having also near its lower end liquid-delivering openings orpassages.

In testimony whereof I affix my signature in presence of two subscribingwitnesses.

CHARLES A. CLARK.
